1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundChanges in immune cell and inflammation-associated protein levels, either independently or in combination, are commonly used as prognostic factors for various cancers. The ratio of lymphocyte count to C-reactive protein concentration (lymphocyte-CRP ratio; LCR) is a recently identified prognostic marker for several cancers. Here, we examined the prognostic value of LCR and its relationship to various aspects of the tumor immune microenvironment in patients with intrahepatic cholangiocarcinoma (ICC).

methodsThis was a single-center, retrospective study of patients who underwent surgical resection for ICC between 1998 and 2018. Patients were dichotomized into high- and low-LCR status groups, and the relationships between LCR status, prognosis, and other clinicopathological characteristics were analyzed. Tumor-infiltrating CD8+ and FOXP3s+ lymphocytes and tumor expression of CD34 and programmed death-ligand 1 were evaluated by immunohistochemical staining of resected tumors.

resultsA total of 78 ICC patients were enrolled and assigned to the high (n = 44)- and low (n = 34)-LCR groups. Compared with the high-LCR group, patients in the low-LCR group had a significantly higher serum CA19-9 level (median 20.6 vs. 77.3 U/mL, P = 0.0017) and larger tumor size (median 3.5 vs. 5.5 cm, P = 0.0018). LCR correlated significantly with tumor microvessel density (r = 0.369, P = 0.0009) and CD8+ T lymphocyte infiltration (r = 0.377, P = 0.0007) but not with FOXP3+ T lymphocyte infiltration or tumor PD-L1 expression. Low-LCR status was significantly associated with worse overall survival by multivariate analysis (P = 0.0348).

conclusionsLow-LCR status may reflect a poor anti-tumor immune response and predict worse outcomes in ICC patients.
